Social Identity in the 21st Century-Time for Individual Countermarketing Tools?

I just read parts of the US Army Manual, FM34-60 COUNTERINTELLIGENCE ( I have way too much time on my hands), and a thought occurred to me. We all have, or should have, firewalls for our personal computers, passwords for our banking and communication over the internet, etc. But what about consumer tools that have been specifically designed to act as “countermarketing” aids? And if they exist, what do they look like, how are they configured, and managed? It may be a bit of a stretch to visualize, but for me, it might mean that I can begin to manage how I want various companies to incorporate my internet behavior into their computerized marketing machinery. Imagine the possibilities. If enough people used such a tool, it might even force companies to do the hard work. Actually get to know me.
